REFLECTOR: Franklin Will not turnover when hot

[Rene Dugas]

Larry,

I may not be understanding this note but if you extended the scoop is there
just more space or are you blowing air from the scoop over the pan and
accessory case.  This cooling air is coming from where?

If it opens under the engine, I do not see how you obtain the cowl vacuum we
all want for downdraft cooling.  I must be missing something.  Help?  I like
the scoop.  Mine is whimpy in comparison so please be gentle but I get 1" of
increased manifold pressure.  What do you do with all that air?

Rene'

Mike & WJ,

 

My brother made two starter nose pieces, the first of which is shown in the
photos.  The recess where the mounting bolts go are machined on the wrong
side.  Number two is in use.  I think that your hot start problems are
related to heat soaking the starter motor and the reason for the third
picture.  My belly scoop is extended down 1" to increase air flow over the
oil sump and the accessory case.  I wasn't so concerned about the starter
but the alternator getting too hot.  I have #2 wire and never a hot start
problem.  A plenum mounted blast tube for the starter might be the solution.

 

Mike.  You may be able to use my "spare" nose piece if you trim off the
mounting ears and add an "L" shaped bracket to clamp the starter in place.
If you want it email me off reflector with your address and I'll send it to
you.

P.S.: My brother is retired and no longer has access to a machine shop.

Larry,

Mine came with the same starter and adapter plate. I replaced the original
starter with a skytex and then a ford (NAPA 2446115),
but still the same problem. I have never had a problem with adapter plate,
but you are right, it is poorly made and is
prone to leak oil back into the starter solenoid. Would your brother
consider making one for me? PM me if he can.

Mike,

 

My Franklin came with a Honda Civic starter with a very poorly made,
welded-up adapter plate.  Luckily my brother was a tool and die maker and
produced an adapter of my design from an aluminum billet.  The battery is a
55 AHR Optima deep discharge with #2 wire.  Never a starting problem.
